EMIL J. P. MEYER, OF CHCAGO, ILLINOIS.

CAR CONSTRUCTION.

To all 'io/tom 'it may concern Bo it known that l, EMIL J. F. MEYER, acitizen ot the United States, residing at Chicago, in the county of Cookand State oit illinois, have invented certain new and uset'ulImprovements in Car Construction, oit which the iollowing` is adescription.

My invention belongs to that gene 'al class ci devices in carconstructions known as car holsters, and relates particularly to animproved truck bolster and a cooperating body or cross bolster.

rlhe invention has among its objects the production oit a device oit thekind described that is simple, convenient, efficient, durable, compact,and satisfactory.

it has among` its further objects the production of a device in whichthe truck may be removed trom the car with a minimum of labor and time,should the ease require the removal, and a construction in which thebedy bolster may, in an emergency, be carried by almost any oit thetrucks now in use.

'llo this end my invention consists in the novel construction,arrangement, and combination of parts herein shown and described, andmore particularly pointed out in the claims.

in the drawings, wherein like reference characters indicate like orcorresponding parts, Figure 1 is a top plan view oi' the body and truckholsters. F ig. 2 is a perspective view of the oil cup cap or plate 2t.Fig. 3 is a perspective view of one of the key members 6. Fig. 4 is apartial sectional view taken substantially on line 4, 4 of Fig. 1. Fig.5 is a top plan view of the truck bolster, the body bolster removed.Fig. 6 is a cross sectional view taken substantially on line G, 6 or'Fig. 4. Fig. l is a sectional view of the body bolster, illustrating theuse of the saine with the well known type of truck bolster. Fig. 8 is aperspective view of the detachable post and top part of the truckbolster. Fig. 9 is a side elevation of a portion ot a modiiiedconstruction et truck bolster. Fig. 10 is a similar view of anotherconstruction, and Fia'. 11 is a similar view of stillanother modifiedconstruction.

Referring to the drawings, 1 represents the truck bolster, and 20 thebody bolster, which is preferably provided with the extending parts 30on each side, forming; what is commonly known as a cross bolster, orreally a cross body bolster. llt may be mentioned at this time that lhave not illus- Speeicaton of Letters Patent.

trated the complete car, nor have l shown in detail how the truckbolster is carried by the truck, or the car body by the body bolster, itbeing` understood that these constructions may be as preferred. rlhepresent invention resides particularly in an improved connection betweenthe holsters, or between the truck bolster and car body. The holstersare preferably east steel; however, portions may be oit cast steel andothers oit pressed steel, or the entire device constructed of pressedsteel, or in an equivalent manner.

The truck bolster 1, which is suitably carried by one ci the trucks, isneterably centrally recessed or eut out as at E3, the ends 3 ot' therecess being beveled or inclined, as shown. Arranged to seat in therecess is a removable bolster part or top 4, preferably having endsinclined substantially to conform to the ends 3 of the recess. Theremovable top part, however, is made shorter than the recess, and keysor gibs G inserted as shown. Referring particularly to Fig. 6, it willbe noted that the sides oi" the detachable bolster part 4 are extendeddown as at 4, so as to bear against each side of the bolster part 1, andprevent the transverse displacement of the parts. rllhe keys 6 arepreferably provided with heads 7, which lock the keys against endwisemovement, as well. as lock the two bolster parts against transversemovement relative each other. The keys 6 may be locked in position inany desired manner. lis shown, lugs 9 are provided on the bolster part1, and similarly formed lugs 10 on the part 4, and plates 8 arranged asshown and locked in position by pins 11. By this construction the twobolster parts are as firmly secured together as itt they were :termedintegrally.

Extending' from the upper side or top of the removable part 4 is a post14. The post 14 is preferably chambered and provided with a centrallyextending pin 16, the same being braced and the post strengthened by thepartitions 18, or Ithey may be termed spokes or spiders. Openings 17 areprovided from each chamber through the wall 14, and in operation somepreferred lubricant is placed in each oit the' chambers 15. Thelubricant may pass through the openings 17 for lubricating` the parts,as hereafter described.

llhe body bolster 20, as before mentioned, may be constructed of anysuitable material,

and is provided with a bearing part or member 21 at the center. As shownin the drawings, it is also extended upon each side at 30 for theattachment of the center beam or beams of the car. rEhe bearing part 21is arranged to seat upon the surface 22 of the post 14, so as to supportthe bolster and the car body carried thereby. The upper part ispreferably formed as at 23, to bear against the upper part of the post,which is dust or dirt reaching the bearing. ArrangedV at the top of thepost is a plate 25, which bears against the end of the post and the endof the bearing 21, the same be'ing extended slightly as at 26 to theinterior of the post. The same is also extended as at 27 upon the upperface for the purpose described hereafter, and secured in position in anysuitable manner, as shown, by a pin 2S passing through the extendingpart 16 of the post 14. TVith this construction the post and bolster aresecurely locked together, and the chamber' 15 closed at the top.

As before mentioned, the body bolster is provided with the extendingparts 30 for attachment to the center beam of the car. rIhe particularconstruction of the car frame or body, however, may vary to aconsiderable extent, depending upon the preference of the carmanufacturer or user, and I therefore do not wish to be understood aslimiting myself to the exact construction of body bolster, etc.,inasmuch as the bearing part 21 may be secured to the center beam, orother part of the car frame, the two sides of the bolster being securedto those parts. lVhere the body part or frame of the car is of pressedsteel, or other construction, the cross bolster shown might be entirelydifferent.

In case it is desired to remove the truck from the car body, the' bodyof the car is jacked up sufficiently to take all weight or pressure oftof the bearing 22 at the base of the post. It will, of course, beunderstood that it is necessary to jack up the car sufficiently to takeoif any pressure on the springs of the truck, after which the plates 8and the keys 6 are removed. The body is then further jacked until theextending part 4 is above the edge 2 of the recess, so that the truckcan be removed out from under the end of the car. The pin 28, ifdesired, may then be removed, permitting the post and bolster part 4 todrop. If it is desired to place a new truck under the car, and the truckhaving a bolster similar to that shown is not at hand, the common typeof truck may in an emergency be used. In this case the plate or cap 25is removed from the top of the car bolster and secured in position atthe lower' end of the bearing 21 with the extension 27 downsubstantially as shown in Fig. 7. The plate 25 is then secured inposition by bolts 31 extending through the holes 31 of the plate, andengaging in the bosses or extensions 29 (shown in dotted lines inFig. 1) on the lower end of 2-1. 'I he other form of truck having thebolster 45 with the plate 46 thereon, may then be placed under thebolster 20, and the body lowered so that the extension 27 tits in therecess in the top of the truck bolster 45. I have not considered itnecessary to illustrate in detail the emergency truck bolster, thisconstruction being familiar to those skilled in the art.

Referring particularly to Figs. 4 and 5, it will be noted that holes 50are indicated in the bolster 1. These holes are placed there so thatsuitable side bearings 49 may be attached to the bolsters when anemergency truck is used, as illustrated in Fig. 7, if the same isdesired. This permits the car to be used while being returned forrepairs, since the same may be operated as well as one of the well knowntypes of bolster connection. A pin or bolt 4S may be positioned throughthe opening substantially as shown. This gives an emergency repair andillustrates how the device may be used with different trucks and truckbolsters.

I have shown the truck bolster provided with ribs 32 for reinforcing thesame, and the detachable part 4 with ribs 34. The body bolster is shownwith reinforcing ribs 35 connected by the webs or spiders 36. This isfor the purpose o-f illustration, however, for, as previously mentioned,the general construction of the holst-ers may vary.

In Figs. 9, 10 and 11 several modified constructions are shown, forattaching the part 4 to the part 1. Referring to Fig. 9, 8T (whichrepresents the bolster part 1 shown in the igures previously described),is the bolster of the truck, and 3 the removable bolster part, the partsbeing locked or secured together by bolts 39. In Fig. 10, the parts 40and 41 are secured together by keys 42, the keys being locked inposition in any suitable manner. In Fig. 11 the parts 43 and 44 areformed as shown, the part 44 at each end being engaged by the extendedpart 45. IVith this Construction any form of keys or locking bolts,similar to any of those described, or their equivalents, may beemployed.

Having thus described my invention, it is obvious that variousimmaterial modifications may bemade in the same without departing fromthe spirit of my invention,
